Aquaterra:
[Jonathan Benjamin at Flinders University] is part of a small band of underwater archaeologists who are raising their ambitions. To them, the seabed isn’t an inconsequential backdrop on which wrecks fester. It is a vast and complex drowned landscape, scattered with the remnants of ancient human lives. Since the ice sheets were at their peak about 20,000 years ago, rising seas have drowned at least 20 million square kilometres of coastal territory around the world – an area almost as large as the North American continent. Some even think of it as a lost, fragmented continent. They call it Aquaterra.
